Application filed my 12,

- My invention relates vto improvements in door ventilating mechanlsms. It relates particularly to structures in which a door is provided with a ventilating o ening therethr'ough, and having a closure inged thereto'for closing the opening.

One of the objects of myinventlon is to provide novel mechanism by which the door character which are already built or in use.

The novel features of my invention are hereinafter fully described and claimed. p In the accompanying drawing, which illustrates the preferred embodiment of my invention,

Fig. 1 is a top view, partlybrokenaway and partly in section of myimproved mechanism shown attached to a door.

Fig. 4 is a vertical cross sectionof the closure shown open and parts connected therewith. I v r Fig. 5 is an enlarged sectionthrough the screw and nut, shown in the positions occupied by them when the door is open.

l-designates a door hinged in the usual manner to a door frame 2, and provided with an opening 3 therethrough, for ventilation purposes, the door having hinged to it adjacent to the lower edge of the openis adapted to be swung from the closed position, Fig. 2, to theinclined positionshown in Figs. 1 and 4.

The closure 5 is provided with the usual end of which is pivoted by a "1928. Serial No. 277,380.

overlapping slats 6 arranged to fold over each other when the closureis shut.

7 designates one wall in which the frame 2 is mounted, and 8 designates another wall at right angles thereto and at the right of and closely adjacent to the frame 2. I

.With a wall -8 so close to the door, if the closure 5 should be open when thedoor. 1

is swung to the position shown in dotted lines in Fig. 1, the closure would strike the wall and so might mar the wall or damage the closure, mechanism. Myinvention is de-v signed to preventsuch marring or damaging, by having theopening movement of the. door serve to swing the closure5 toward the tion, as may be required.

To effect such closing of theclo'sure with the opening movement of the door, I pro vide means which connects the door with the frame and with the closure, and which, prefe'rably comprises the following described parts.

A member 9, which may be a nut, is oscillatably mounted on a vertical axis in a recess 10 in the upper edge of the door 1. The member 9 has .a horizontal arm 11 above the 70. closed position, or to the fully closed posiby door, said armbeing pivoted by a vertical 7 pin 12 to one end of a horizontal link 13, disposed between the doorl and the top of the frame 2 and pivoted by. a vertical pin 14 .to

the under side of the 'top of the door frame 2. Rotat-ably fittedin the nut 9 is a screw 15 .which is soldered or brazed,'or otherwise in tegrallyconnectedwithand forms a part of a link 16, the free end of which is pivoted: by a, pin 17 to one end of a link 18,v the other pin '19 to the upper edge ofthe closure 5 I When the door 1 is closed,and the closure is swung to and from the open position,the links 16 and 18 will'fold and unfold, and in the folded position will be between the upper edge of the closure 5 and the portion of the door over the opening3, as shown in Fig. 2. 'l/Vhen the closure 5 is open, the links 16 and 18 willbe extended, as shown in Figs. 1, 3, land6.-"x As the link '16 swings toward the folded position, Fig. 2, the screw 15, forming a part thereof, will unscrew and lower in the nut 9, and as the closure moves toward theopen position, the screw 15 will screw upwardly into thenut in extent.

the position shown in dotted lines in Fig. 1, will swing the closure 5 to or toward the closed position, to prevent the closure striking the wall 8, there is fitted in the nut 9 above the screw 15, a stop screw or abutment 20, which is vertically adjustable in the nut. When the door is closed and the closure is swung to the fully open position, shown in Figs. 1, 3 and 4, the screw 15 will be in con-' thereby swinging the link 16 inwardly, and

by means of the link 18 drawing the closure 5 to the closed position, or toward the closed position, depending on the position of the screw 20 in the hut,

When the door is closed, the closure 5 may be swung to and from the open position, without the movement of the screw 15 being interfered with by the stop screw 20, as in closing the closure, when the door is closed, the screw 15 draws away from the stop screw 20, and only contacts therewith when the closure is open.

By adjustment of the screw 20, the open ing movement of the closure 5 may be varied I do not limit my invention tothe structure shown anddescribed, as many modifications, within the scope of the appended claims, may be: made without departing from the spirit of invention.

What I claim is 1. In a door ventilating mechanism, the' combination with a door frame, a door hinged thereto. having a ventllating' opening therethrough, and a closure for said opening movable on said door to and from a closed position, of means connecting the doorwith the frame and closure and, actuated by the door in opening for moving the closure toward the closed position, in case the closure is in theopen position.
